Shannon compression

Task

Implement shannon algorithm for file compresion.

Features

• GUI with progress bar
• Implemented as lib
• XOR supported

How to run

git clone https://github.com/ZavaruKitsu/shannon_compression
cd shannon_compression

# setup virtual environment
python -m venv venv
pip install -r requirements.txt

# run gui
python main.py

Project structure

main.py

Entry point.

diff.py

File for testing the correctness of (de)compression.

src

consts.py

Just a bunch of constants.

azar.py

Wrapper around writers.

utils.py

Contains get_binary_repr that returns binary representation of any integer (including float).

src.encoders

base.py

A bit of abstractions.

shannon.py

The shannon algorithm itself.

caesar.py

XOR encryption.
